Agricultural and mechanical control. Agricultural control measures include crop rotation, application of decomposed manure, rational close planting, and deep plowing. Physical or mechanical control is to use a lawn mower to cut off the upper part of the weeds and reduce the amount of seeds before the flowering period of the exotic creatures.
Artificial control. Artificial control is suitable for invasive species that have just been introduced, settled, and have not spread widely. Artificial control can quickly eliminate pests in a short period of time, but it is ineffective for plant seeds and some harmful animals that have sunk into water and soil; harmful plants with high fecundity are prone to growth again, so they need to be controlled every year.
Biological control. That is, in the place where pests are introduced, by reintroducing the mutual adjustment and mutual restraint mechanisms between pests and natural enemies by introducing natural enemy factors in the country of origin, this ecological balance can be restored and maintained. Therefore, biological control can achieve the results of biodiversity conservation using biological diversity.
Alternative control. In other words, invasive plants are replaced with native plants that have economic or ecological value.
Turning waste into treasure. Vicious weeds, especially toxic weeds, have some special substances or competitive substances in their bodies. Research and use of these substances can be used as plant-derived pesticides, or further research as new lead compounds for the development of new insecticides, fungicides, herbicides. According to reports, the substance extracted from Eupatorium adenophorum produces a dye that is not only colorful but also resistant to insects. Manzanella is a Chinese herbal medicine that can cure pneumonia, hyperactivity cough, bronchitis, colds, edema, and stroke.
Chemical control. Chemical herbicides are the most effective weapons for controlling weeds. It has become an indisputable fact. The first is that the effect can be quickly achieved; the second is that the user avoids direct contact with poisonous grasses for a long time and effectively protects the user's safety; thirdly, in a relatively short period of time, the goal of controlling grass and restoring the ecology is achieved. Therefore, chemical control has significant economic, social, and environmental benefits. Indiscriminate use or abuse of herbicides can cause problems such as injury to medicines and environmental pollution. Therefore, it is extremely important to use herbicides scientifically.
In short, it can be said that for most exotic vicious weeds, targeted high-efficiency, safe, and low-pollution chemical control methods can be developed. In the prevention and control of harmful weeds, according to local ecological conditions, quarantine and other legal means should be adopted to control their spread and spread, and comprehensive measures such as agriculture, biology, physics, and chemistry should be adopted to control the harm of harmful weeds and force grass populations. Degradation, the establishment of beneficial plant communities, so as to achieve ecological restoration, long-term control of grass damage goals.
Vicious weed control strategy
Malicious Weed Control Strategies Malignancy and miscellaneous crops have wide adaptability, strong fertility, and can quickly spread into dominant populations; and most of them are perennial weeds with developed roots and are difficult to control. Therefore, the following measures are recommended for the prevention of these miscellaneous defects:
